‘The one thing that hasn’t changed is our fares, as we continue to offer Europe’s lowest airfares, with the biggest route network and best service.’

When asked by Mirror.co.uk about the negative backlash the ‘sale’ has garnered, a spokesman responded: ‘We’ve had a phenomenal response to our €/£19.85 seat sale with a million seats on a great range of routes across our network on sale from now until Sunday, as we celebrate 30 years of low fares.’

The sale ends at midnight this Sunday, and the cheap flights offered are between September and January.
